I'm pretty satisfied with the frame line guides we have. That said, I would like 1:1, 1.2:1, and 2:1.• The main reason for 1.2:1 is if I'm shooting 1.2:1 3K mode without anamorphic glass I would like the frame guides to match that frame size since the 1.33:1 guides don't match perfectly.• 1:1 is useful in case someone needs me to shoot an Instagram video. It happens. And although Instagram takes 1.78:1 videos the 1:1 aspect ratio is the main Instagram ratio.• 2:1 only because it has emerged from RED as another frame size.
